Pakistani forces fired four rockets in villages around the Attari border, drawing retaliation from the Border Security Forces.
BSF officials said while two rockets landed in an agricultural field in the border villages around Attari last night, the other two failed to explode.
No casualty has been reported.
According to sources, BSF troops present during night duty opened retaliatory fire.
Official said that due to the dense fog, BSF personnel faced difficulties in finding the exact location where the two rockets fell and exploded in the agriculture fields.
He said the two rockets which did not blast after falling on Indian Territory were traced at Kahangarh post of the BSF.
Immediately after the incident, the BSF held a flag meeting with Pakistani counterparts who denied any firing from their side.
